Electrical Instrument cluster does not function

I would remove the cluster and check the wiring for shorts to the fuse box.

The instrument cluster is a hybrid electronic cluster (HEC) with two basic configurations, the base cluster and the optional instrument cluster. In addition to the two basic configurations, the SVT uses a modified optional cluster in combination with a separate oil pressure and oil temperature cluster. The base instrument cluster, optional instrument cluster and the oil pressure and oil temperature cluster receive and output information utilizing both hardwired circuitry and the standard corporate protocol (SCP) or the controller area network (CAN) communication network (2.3L only). It is very important to understand:

• where the input originates from.
• all the information necessary in order for a feature to operate.
• which module(s) receive(s) the input or command message.
• does the module which received the input control the output of the feature, or does it output a message over the SCP or CAN network to another module?
• which module controls the output of the feature. Its more then likely you need a new instrument cluster.

Hi, this is a pretty common problem on these Silverado instrument clusters. We can definitely help you out with that. Click here to learn more about these Silverado instrument cluster problems: Dr Speedometer Instrument Cluster Repair Speedometer Repair Guage...

Take your truck to a GM dealer and have the Body Control Module checked. The bcm controls most electrical and display functions inside of your vehicle.

did you check the fuse?
that sounds more like the problem!!!

check ignition fuse to dash lights.if all is good you could have pcm problems.

On the rear of the instrument cluster there should be a resistor. This is how the fuel and temp guages are limited to a certain voltage decreasing the power to them so that they dont burn out. These (voltage limiters) resistors are available seperately from the dealership.

oil ressure sending unit needs to be replaced. Most are located near or at the oil filter mount location.

hello,good day,maybe your cluster nearly damage,send to your dealer,they have a testing procedure(simulation all the gauges), to determine if your cluster is defective,ty

hey if it was constantly running at these temps you would dhave definately damaged the engine by now. the temp guage is integrated with the instrument cluster and not replaaceable unless the whole guage cluster is replaced. you could go to a professional installer and have an aftermarket temp guage installed. much cheaper than having your instrument pannel replaced. in addition to the instrument pannel being replaced the odometer millage must be programed into the new pannel. if the fans are not turning on the engine more than likely is not getting hot enough to turn them on. but just to be sure i would take the vehicle to a automotive diagnostic specialist to make sure the ecm (electronic control module) is performing correctly. it may not be sending the signal to the fan relay to turn the fan/ fans on. you may also have a faulty temp sending unit. good luck.
